Fastjson 구문 분석 Tree
import com.alibaba.fastjson.*;
JSONObject jsonObj = JSON.parseObject(jsonStr);
Fastjson 구문 분석 POJO
import com.alibaba.fastjson.JSON;
Model model = JSON.parseObject(jsonStr, Model.class
Fastjson은 POJO Generic을 구문 분석합니다.
import com.alibaba.fastjson.JSON;
Type type = new TypeReference<List<Model>>() {}.getType();
List<Model> list = JSON.parseObject(jsonStr, type);Fastjson 변환 POJO를 json 문자열로
import com.alibaba.fastjson.JSON;
Model model = ...;
String jsonStr = JSON.toJSONString(model);
Fastjson POJO를 json 바이트로 변환
import com.alibaba.fastjson.JSON;
Model model = ...;
byte[] jsonBytes = JSON.toJSONBytes(model)
Fastjson POJO를 json 문자열로 OutputStream
import com.alibaba.fastjson.JSON;
Model model = ...;
OutputStream os;
JSON.writeJSONString(os, model);;
에 기록
Fastjson은 POJO를 Writer
import com.alibaba.fastjson.JSON;
Model model = ...;
Writer writer = ...;
JSON.writeJSONString(writer, model);
